Awareness ...

In my understanding based my present Awareness ... Mind is tool in the hands of Atman to have Experiences as desired ...

Atman is the powerhouse; Mind receives energy to function from the atman.

As clarified by Lord krishna [Cp. 15] ... "Adhishthaaya Manashaayav vishyaanupasevate" … So when mind is unaware of "something", "it" doesn't get registered in Mind.

e.g. Difference in degree of awareness we talk about in Hearing & Listening.

"Awareness" is not operational in it's nature; it is the state of Mind [Might be enriched past sundry experiences].

Satsang with Masters, Dhyaan, knowledge [that leads to the divine], Nishkam Karma [that leads to the divine], selfless service to the children of mother earth [whilst maintaining the dignity of needy], Devotion for the divine [without expectation], Abhyas Yog [Spiritual Sadhana] etc. ... can take us to the highest realms of our existence ... slowly & steadily.

Growing in Awareness happens by uncovering, soul being 100% aware ... at all times but Mind is not, because of Mind's union with trigunatmak Prakriti.

Life is best teacher but it can also generate negative impressions & growing in higher awareness [leading Mind towards the divinity] might get stopped for some duration of time.

Hence Yog Sadhana is required to be practised during all different situations of life with complete faith & surrendure.

Finally, when Mind reached that 100% level of awarness as that of the Self; Mind's role comes to an end and it vanishes/mearges with the Soul wherein Mind = Soul [as there is nothing to uncover further].

This process is the trasformation of Mind ... from the lower awareness to the highest possible level of awareness of our own existence.

NB: Absolute "Awareness" always remains the same [Atman being knower of everything at any point of time].
